Abstract
An installation for carrying out a continuous multi-stage industrial process includes a housing that defines a first space and a second space that is connected to the first through a first connecting channel. Different pressure conditions prevail in these spaces during the course of the process. A process material is passed sequentially through the first space, the first connecting channel and the second space. A transported material is provided in the first connecting channel to form a free-flowing sealing zone with the process material and ensures that different process conditions will be maintained in the two spaces, and in particular that different pressures will be maintained in the two spaces. The invention also relates to a multi-stage continuous industrial process using such an installation.
